Similarity-Based Indexing and Integration of Protein Sequence and Structure Databases. Start date: Aug. 15, 2008. Expires: July 31, 2009. Awarded amount to date: $157,998. Principal investigator: Hakan Ferhatosmanoglu. Sponsor: Ohio State University Research Foundation.
Funds development of database indexing and similarity search technologies to manage, analyze, and integrate protein sequence and structure databases. The project will use a “unified theme” for both protein sequence and structure data, according to the grant abstract, based on “extracting key features and mapping them into compact feature vectors spaces to facilitate construction of integrated index structures with sensitive, accurate, and efficient querying capabilities,” the grant abstract states. For the sequence data, the project intends to develop feature-extraction methods that involve physiochemical properties of the amino acids and detect low level of similarities. For the structural data, the project will develop methods to capture local structural motifs using contact maps and spatial motifs. The software and the results of the project will be available here

Supports an initiative to generate “substantially complete metabolic reconstructions for all sequenced microbial genomes,” according to the grant abstract. The approach involves an iterative process of identifying areas of metabolism encoded in microbial genomes that are not yet represented in public databases, creating new reaction network components for them, and generating updated metabolic reconstructions. The database of metabolic components and software will be fully integrated with the SEED comparative genome annotation and analysis environment, and the principal investigators will collaborate with the SEED community to disseminate the research results, the abstract states.

Supports a project to improve the analysis of mass spectrometry data for biomarker discovery. Goals of the project include investigating data-preprocessing algorithms for label-free quantification of peptides in serum using liquid chromatography/mass spectrometry, and investigating feature-selection algorithms that can isolate subgroup-specific biomarkers.

This project focuses on computational approaches to address “a subset of the problems that could arise in a typical whole-genome based association study,” according to the grant abstract. These problems include phasing of genotypes into haplotypes using overlapping sequence data and fast filtering for pairs of loci that interactively influence a phenotype and its application to multiple-locus testing of common disease phenotypes.
Adaptive Integration of Structured and Unstructured Data from Many Sources in a Biological Domain. Start date: Sept. 1, 2008. Expires: Aug. 31, 2011. Awarded amount to date: $443,128. Principal investigator: William Cohen. Sponsor: Carnegie-Mellon University.
Supports the development of a system “that learns to more accurately integrate the many heterogeneous sources of information that are relevant to a single scientist's research needs,” the grant abstract states. The system works by “loosely” integrating data of many different types, including unstructured text, into a single-typed directed graph, and then querying the graph using a query language that allows “schema-free similarity queries,” which specify a set of query terms and constraints on the desired output. The result of a query is a ranked list of entities that are ordered by similarity to the query terms. After a query, a user can label any of the suggested answers as “relevant” or “non-relevant” in order to drive a “learning phase” with the goal of producing a better ranking for future queries.

The investigators plan to address “the theme of emergent phenomena in biological complex networks with novel concepts from non-equilibrium systems and complexity, and to systematically transform these theoretical concepts into practically applicable models of functional modules.” In order to achieve this goal, the investigator will study functional modules by clustering and renormalization methods.
